Use chrome.browserAction.getBadgeText:

chrome.browserAction.getBadgeText({}, function(result) {
    alert('Badge text = ' + result);
});

This method (like most of the Chrome extension API) is asynchronous, so you need to specify a callback function that receives the result.

Answer by Rob W is returning blank result for all tabs. Adding tab.id worked for me:

chrome.browserAction.getBadgeText({ tabId: activeTab.id }, result => {
    alert('Badge text = ' + result);
});

In the Chrome extension API v3, the chrome.browserAction API has been replaced with the chrome.action API.

To set the badge text:

chrome.action.setBadgeText({text: '<number_of_new_tweets>'});

To get the badge text:

chrome.action.getBadgeText({}, function(result) {
  var badgeText = result;
  console.log("Badge text: " + badgeText);
});

The usage is similar to the v2 API, but note that chrome.action is used instead of chrome.browserAction in Chrome extension API v3.
